在python上按路径上载视频文件不工作

我试着用python上传视频文件，问题是即使我写了文件的路径，系统也找不到文件。我的代码如下：

import os
import requests

#step 1
host = 'https://blablabla.com'

test = {
    "upload_phase" : "start",
    "file_size" : 1063565
}

params = {
    "access_token":my_access_token, 
    "fields":"video_id, start_offset, end_offset, upload_session_id", 
}

vids = requests.post(host, params=params, data=test)
vids = vids.json()

try:
    video_id= vids["video_id"],
    start_offset= vids["start_offset"],
    end_offset= vids["end_offset"],
    upload_session_id= vids["upload_session_id"]
except:
    pass

print(vids)

###############################################################################
#step 2
###############################################################################
test = {
    "upload_phase" : "transfer",
    "start_offset" : start_offset,
    "upload_session_id": upload_session_id,
    "video_file_chunk": os.path.realpath('/home/def/Videos/test.mp4')
}

params = {
    "access_token":my_access_token, 
    "fields":"start_offset, end_offset", 
}

vids = requests.post(host, params=params, data=test)
vids = vids.json()

try:
    start_offset= vids["start_offset"],
    end_offset= vids["end_offset"]
except:
    pass

print(vids)

我尝试了很多方法，

比如os.path.abspath、os.path、os.path.dirname、os.path.basename、os.path.isfile、os.path.isbs、os.path.isdir

它仍然不起作用。即使我在代码中给出import os.path或import os

，您也只是将路径作为字符串发送到服务器，而不是文件本身。您应该尝试以下方法：

my_file = {'file_to_upload': open(os.path.realpath('/home/def/Videos/test.mp4'),'rb')} 
# You should replace 'file_to_upload' with the name server actually expect to receive
# If you don't know what server expect to get, check browser's devconsole while uploading file manually
vids = requests.post(host, params=params, files=my_file)

还要注意，您可能需要使用

requests.Session（）

才能处理cookie、访问令牌
